Abstract. Research on the sponge barnacle of Indonesia is very rare, and this study is aimed to describe the morphological characteristics of sponge barnacles and their specific relationship with their sponge host species. This research was a survey and sponge samples were collected by tearing apart any available sponge found in three sampling locations, typically coral reef areas of Weh Island, Seribu Islands, and Karimunjawa Islands. Sponge barnacles contained in sponge samples were observed using stereo microscope and scanning electron microscope, and species identification was determined based on the morphological description of Darwin (1854), Pilsbry (1916), Martin dan Davis (2001), and Kolbasov (1993). Four species of sponge barnacles were found consisting of Acasta cyathus, Acasta fenestrata, Euacasta dofleini, and Membranobalanus longirostrum. Specific relationships of barnacle and its sponge host were found between Euacasta dofleini and Haliclona sp. and between Membranobalanus longirostrum and Suberites sp. respectively.

Abstract

Krendet is one of the fishing gears used to catch Lobster in the South Coast of Java. Krendet is a passive fishing gear. Lobster is a fishery commodity that has high economic value. This research was conducted to determine the difference in lobster catches based on differences in fishing time and bait types on Krendet fishing gear. The method used in this research is experimental fishing with 4 treatment combinations and 6 repetitions. The difference in fishing time used was morning – afternoon and afternoon – morning, while the bait used was trash fish and no bait as a control. This research was carried out in February 2021 in the waters around the Sadeng area, Gunung Kidul. The analysis carried out in this study used the Two Way Anova Test method. The results showed that the time difference had an effect on the number of catches. The effective time to catch Lobster is at night. This can be caused by Lobster's behavior or habits which tend to be active at night. Giving bait to Krendet is also able to increase the number of catches. The trash fish bait is able to lure the Lobster to come closer to Krendet. Giving bait to Krendet is also able to increase the number of catches. The trash fish bait is able to lure the Lobster to come closer to Krendet so that the Lobster can be trapped.Keywords:KrendetLobsterCoastal Fishing PortSadeng

Abstract

Abstract. Badung Strait generally have nutrient distribution patterns influenced by Sea-atmosphere interactions. The waters of the Lombok Strait is also branching traversed by Indonesian Throughflow (ARLINDO), which will be followed by Indonesian Throughflow variability of sea surface temperature changes. The distribution of nutrients is closely related to light intensity to produce primary productivity. The purpose of this research was conducted to determine the distribution of nutrient concentration and light intensity and chlorophyll-a in Badung Strait during Southeast Monsoon (June 2014). The variables investigated are the concentration of nitrate, phosphate, ammonia, light intensity and chlorophyll-a. The results showed the average value of the concentration of nitrate, phosphate and ammonia at 0.01106 mg/L, 0.01 mg/L and 0.13475 mg/L. The average value of the light intensity at 272.8775 W/m2 and the average value of chlorophyll-a concentration of 0.40925 mg/L. The visualitation images show that there is homogeneus pattern for the phosphate concertration and konvergen patterns for the other paramaters. It is cause of physical parameters influence when obtain the waters sample. Based on the result, it can be conclude that the waters productivity of Badung Strait, Bali is in good condition. The role of other water quality parameters such as temperature, salinity and dissolved oxygen also supports fertility waters.Keywords: nutrients; light intensity; chlorophyll-a; water quality; Badung StraitAbstrak. Perairan Selat Badung secara umum merupakan perairan yang memiliki pola sebaran nutrien yang dipengaruhi oleh interaksi Laut-Atmosfer. Perairan tersebut juga merupakan percabangan Selat Lombok yang dilalui oleh ARLINDO (Arus Lintas Indonesia), dimana variabilitas ARLINDO akan diikuti oleh perubahan suhu permukaan laut. Sebaran nutrien tersebut berkaitan erat dengan intensitas cahaya untuk menghasilkan produktivitas primer. Penelitian ini bertujuan untuk mengetahui sebaran konsentrasi nutrien, intensitas cahaya dan klorofil-a di perairan Selat Badung pada Monsun Timur (Juni 2014). Variabel yang diamati berupa konsentrasi nitrat, fosfat, ammonia, intensitas cahaya dan klorofil-a. Hasil penelitian menunjukkan nilai rata-rata konsentrasi nitrat, fosfat dan ammonia sebesar 0,01106 mg/L, 0,01 mg/L dan 0,13475 mg/L. Nilai rata-rata intensitas cahaya sebesar 272,8775 W/m2 dan nilai rata-rata konsentrasi klorofil-a sebesar 0,40925 mg/L. Hasil visualisasi menunjukkan adanya pola yang homogen untuk konsentrasi fosfat dan pola konvergen untuk parameter lainnya. Hal ini diduga karena adanya pengaruh parameter fisika pada saat pengambilan sampel air. Namun secara umum, berdasarkan data yang diperoleh dapat dikatakan bahwa tingkat kesuburan perairan Selat Badung, Bali dalam kondisi yang baik. Peranan parameter kualitas perairan lainnya seperti suhu, salinitas dan oksigen terlarut juga mendukung tingkat kesuburan perairan.Kata kunci: nutrient; intensitas cahaya; klorofil-a; kualitas air; Selat Badung

Abstract. Genetic diversity information of Gobiidae is needed as a basis for management of its culture or conservation efforts. Mean while, the stability development of the paired organs in animals is closely related to the level of their genetic diversity. In this regard, a study has been conducted to determine of bilateral symmetry characteristics of marble gobies from Jenderal Soedirman reservoir of Banjarnegara and Rawapening Swamp of Salatiga. A survey method was used with purposive sampling technique. The observed variables were abnormalities and meristic bilateral characters. The characters including the number of soft rays on pectoral fins and pelvic fins, and the number of scales on lateral lines. The results showed that both marble gobies from Jenderal Soedirman Reservoir and Rawapening Swamp did not show abnormalities. However, their bilateral meristic characters had been fluctuated, especially for pectoral fins and lateral lines; whereas pelvic fins seem to be symmetry. According to their observed bilateral symmetry characters, in general, it could be concluded that marble gobies from Jenderal Soedirman Reservoir had a better genetic diversity compare to those from Rawapening Swamp. Therefore, it can be used as local genetic resources.Key words. Bilateral symmetry character, marbel gobies, Jenderal Soedirman Reservoirs, Rawa pening Swamp

Abstract

White shrimp (Litopenaeus vannamei) cultivation activities have developed rapidly in Indonesia. White shrimp aquaculture which is carried out intensively with high stocking densities has caused several problems, such as low survival and suboptimal growth. This study aimed to increase the growth, feed conversion, and survival of white shrimp through a combination of probiotics (Lactobacillus sp.) + turmeric flour (Curcuma longa) in feed. The method used in this study was Completely Randomized Design (CRD) with four treatment levels and three replications. The results revealed a significant effect (P0.05) on the value of the daily growth rate (DGR), absolute growth rate (AGR), specific growth rate (SGR), survival rate (SR), feed conversion ratio (FCR), and feed efficiency (FE), but no significant effect (P0.05) on the value of the absolute length rate (ALR). Giving probiotics 10 ml+5 g turmeric flour/kg feed (treatment B) was the best treatment for white shrimp aquaculture, including DGR, AGR, ALR, LPS, SR, FCR, and FE values. Furthermore, the results also revealed that increasing the concentration of turmeric flour in the feed, was negatively correlated to the growth and survival of white shrimp.
